We try to maximise the self-consumption of an energy community endowed with solar panels. We extend the nudging pipeline introduced in our previous work (Improving Energy Consumption Coordination in Renewable Energy Communities through Nudging) . The pipeline first forecasts periods of available excess production, then selectively notifies the households of the community about these periods, to encourage them to consume energy during these periods. The notification logic is performed by a coordinator module. In previous work, the coordinator estimates flexibility at household level. In this work, we do it at appliance level, which offers a finer level of control. The efficiency of our approach is assessed through numerical simulations using semi-real data derived from public consumption datasets. Results indicate that our appliance-level coordinator outperforms the naive strategy which notifies all members about all consumption favourable periods. It also outperforms the corresponding household-level coordinator when any number of notifications may be sent. However, this is no longer the case when the notifications are restricted in numbers. Our results suggest that, to take advantage of the coordinator working at appliance level, appliances should be endowed with automated devices able to activate them upon reception of a signal.
